php post到指定URL——fsockopen

<?php
function sendpost($url, $data){

	if (!$url)
	{
		return "couldn't parse url";
	}
	//将参数拼成URL key1=value1&key2=value2 的形式
	$encoded = "";
	while (list($k, $v) = each($data))
	{
		$encoded .= ($encoded ? '&' : '');
		$encoded .= rawurlencode($k)."=".rawurlencode($v);
	}
	$len = strlen($encoded);
	//拼上http头
	$out = "POST ".$url['path'].(isset($url['query']) ? ('?'.$url['query']) : '')." HTTP/1.1\r\n";
	$out .= "Host:".$url['host']."\r\n";

	}else{
